TPD1018F
TOSHIBA Intelligent Power Device Silicon Monolithic Power MOS Integrated Circuit
TPD1018F
High-side Power Switch for Motors, Solenoids, and Lamp Drivers
The TPD1018F is a monolithic power IC for high-side switches. The IC has a vertical MOS FET output that can be directly driven from a CMOS or TTL logic circuit (e.g., an MPU). The device is equipped with intelligent self-protection and diagnostic functions.
Features
A monolithic power IC with a new structure combining a control block (Bi-CMOS) and a vertical power MOS FET (-MOS) on a single chip One side of load can be grounded to a high-side switch Can directly drive a power load from a microprocessor. Built-in protection against overvoltage, thermal shutdown, and load short-circuiting Incorporates a diagnosis function that allows diagnosis output to be read externally in the event of load short-circuiting, overvoltage, or overheating. Low on-resistance Low operating current : RDS (ON) = 0.8 (max) : IDD = 120A (typ.) (@VDD = 13.2V, VIN = 0V) Weight: 0.08g (typ.)

Pin Description
Pin No. Symbol Function Output pin. When the load is short-circuited and current in excess of the detection current (0.5A min) flows to the output pin, the current limiter operates to protect the IC. Ground pins. Power pin. Incorporates an overvoltage protection function which turns off the output when the voltage applied exceeds 25V (min). Protects IC and load. Incorporates 2V (typ.) hysteresis. Input is CMOS-compatible, with pull-down resistor connected. Even if the input is open, output will not accidentally turn on. Ground pins. Self-diagnosis detection pin. Goes low when overcurrent, overheating, or overvoltage is detected. n-channel open drain.

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/Derating Concept and Methods) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).

Precaution:
1. 2. Since there is no built-in protection against reverse connection of batteries, etc., provide such protection using external circuits. Since this IC does not include a negative bias protection circuit for the output pin, connect a freewheeling diode (FWD) between OUT and GND when negative bias is applied to the output pin.
